The invention relates to a
polymer-based multiferroic magnetoelectric
composite material having both ferroelectric properties and ferromagnetic properties. The
composite material is characterized by being formed through mixing up one-dimensional OD-MFe2O4 ferromagnetic elements with the
fluoropolymer cPVDF material. The one-dimensional OD-MFe2O4 ferromagnetic elements are obtained through growing an MFe2O4 ferromagnetic compound on the surface of a one-dimensional functionalized material, wherein M=Fe, Co, Ni, Mn and Zn. According to the technical scheme of the invention, ferrites (MFe2O4, M=Fe, Co, Ni, Mn and Zn) and
magnetic nanoparticles are loaded on the surface of the one-dimensional functionalized material through the in-situ assembling process, so that the one-dimensional material-magnetic nano-material (OD-MFe2O4) of a specific dimension and a specific surface activity is automatically synthesized. Therefore, the uniform dispersion of ferromagnetic OD-MFe2O4 in a ferroelectric
polymer matrix is realized through compounding the ferroelectric
polymer matrix with ferromagnetic OD-MFe2O4. Meanwhile, the good integration of an inorganic phase and an organic phase is realized. As a result, a ferromagnetic phase is highly ordered in a composite
system. The wholly new multiferroic magnetoelectric
composite material having both ferroelectric properties and ferromagnetic properties is prepared.
